CHIMNEY TOP on VENTILATOR;

srnncnrron' fr-ming pm of Lei-.ters Patent no. 629,253, dated .my 1e, ieee. Application filed October 28, 1898. Serial No. 6941838. (No model.)

To aiZ whom z5- may concern:

' Beit known that I, JOSEPH ALI-IODEL,resid ing in the city of Baltimore and State of Maryland, have invented certain new and useful Improvements in Chimney Tops or Ventilators, of which the following is a speciiication.

My invention is an improvement in chimney tops or ventilators, and has for an object to provide a simple construction involving ro but few parts, which will oder no obstruction to the free outlet of the smoke, will efficiently prevent downdraft, and in which the moving parts are counterbalanced yand maybe' adjusted. I5 The invention has for a further object a novel means by which to secure the flue-pipe to the chimney.

The invention has for further objects other improvements; and it consists in certain novel zo constructions and combinations of parts, as will be hereinafter described, and pointed Y out in the claims.

In the d rawings, Figure l is a perspective view of my improvement as in use. Fig. 2

z5 is a vertical longitudinal section thereof.

Fig. 3 is a detail View of the base-plate. Fig. 4 is a detail view of one of the anchor-bars. Fig. 5 is a detail cross-section on about line 5 5 of Fig. Land Fig. 6 is a detail section on I 3o about line 6 6 of Fig. 2. l The cowl and other operating devices are shown in Fig. 2.y These armsD fit within the slots B2 and are provided with heads D,which overlie the slotted lugs B and have openings I)2 in line with the lugs B2, so the bolts E can be passed up through the slots B2 and ,openy ings D2 and receive the nuts E faswill be understood from Figs. 2and By this.

5o means the base-plate is securely held to the chimney,and the liuc-pipe being bolted to the l base-plate is likewise secured iirmly in place, as desired. f

The top G is arranged above the upper end Y ofthe flue-pipe A and is supported therefrom by the slender uprights or standards F. It isI manifest that these standards F will offer no obstruction to the free outlet of smoke and the like from the fine-pipe, and as these rods are theonly parts intervening the lue- 6o pipe and the top it follows that I secure an unobstructed discharge of the smoke. Upon the top G, I mount the shaft H, which is suitably secured to the top and forms the journal about which the cowl revolves. The cowl includes the guard-plate I andthe vane J, both of which parts are connected with the bearing-piece K, which latter'rests upon and turns on the upper end of the shaftA H. It will be noticed 'that the vane is secured di- 7o rectly to the bearing-piece, while the guardplate is held thereto by means of the arms L. I also employ an arm L', which is secured at one end' to lthe guard-plate and hasy near its other end an opening L2, which; journals on the shaf t H. Itwill be noticed that the guardplate I and the vane J are on opposite sides of the bearing-piece K and so counter-balance each other. To secure'an accurate balancing, I prefer to provide the vane J with a slot J ,in 8o which is placed a bolt J 2, carrying weights J s,

Aand a nut J4, .which construction permits the adjustment of the weightback and forth to secure a proper balancing of the parts, as desired. v 8 5 The guard-plate I is made of a length. sufficient to extend about half-wayv around the top G and has at its ends the outwardly-flared extensions I', which aiford a surface for the wind and facilitate the turning of the top, as 9o 'wellas operate to prevent any downdraft at either side of the guard-plate. I also provide the guard-plate at its upper edge with a flange I2,y which overlaps the top G and extends for ya short distan ce inwardly over said top. This flange I2 is preferred, because it prevents any downdraft at the top of the guard-plate and 1 also permits the outlet of smoke between the top andvflange I2 in calm weather, and so im proves vthe draft. n l roo 1o one-half the circumference of the top G.

5 guard-plate from upward movement.

As shown in Figs. 1 and 2, the guard-plate extends from the point above ldie top G to a point slightly below the upper end of the {inepipe A and in a circular direction for about It thus operates to prevent any doWndraf t when the Wind is blowing, and by the action of the vane and its end wings l the guard-plate is always kept in position facing the Wind, as

I5 is desired.

It is preferred to extend the hearing-piece K slightly at K', asshown in Fig. 2, so it Will tend to shed rain and the like from the bearing L2.-

2o Having thus described my invention, what 25 iiue-pipe,the top supported thereomthe guardplate having a flange overlapping the top and alug or bracket underlying such top, the shaft supporting said guard-plate and carried entirely by the top, the vane connected with the 3o guard-plate and provided With the longitudinal slot and the Weighted bolt adjustable in said slot substantially as set forth.

2. The combination of the flue-pipe, the

uprights thereon, the top supported by such uprights, the shaft mounted on the top, the guard-plate having a flange overlying the top whereby to prevent downdraft and a bracket underlying the top whereby to prevent any upward displacement of the guard-plate, a central bearing-piece journaled on the shaft and arms connecting said bearing-piece with the guard-plate, and the vane connected With said' bearing-piece substantially as set forth.

3. The combination With the top and the shaft carried by and projecting upward from said top, of the bearing-piece resting and j ournaled upon the upper end of said shaft, the guard-plate connected with said bearing-.piece and having a flange overlapping and a bracket underlying the edge of the top plate and the vane connected with the bearingpiece substantially as set forth.

4E. In a chimney top or ventilator thecombination ofthe flue-pipe, the base-plate provided with the radial slots arranged to overlie the chimney-flue, the anchor-rods adjusted to pass thro n gh the slots in the base-plate and having a head overlying the slotted portion of the base-plate and provided with an opening in line with said slots, and the connecting nuts and bolts substantially as` set forth.
